The 330903-03-11-05-02-05 belongs to Bently Nevada's 3300 NSv eddy current probe series. This series is specifically designed for narrow spaces, small shaft diameters, or constrained installation environments and is an important component of the 3500 monitoring system.
Axial (thrust) position measurements
Phase reference (Keyphasor signals)
Tachometer and zero speed measurements
The 3300 XL NSv Proximity Transducer system is intended for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements. The 3300 XL NSv Transducer System design allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 XL NSv system may use the existing probe, extension cable, and monitoring system with 3300 XL NSv Proximitor Sensor. Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, extension cable, and Proximitor Sensor with NSv components.

When using the 330903-03-11-05-02-05 (3300 NSv) probe, it is crucial to pair it with a dedicated 3300 NSv Proximitor; mixing it with standard 8mm Proximitors will cause severe linearity errors. During installation, leverage its narrow-space design by ensuring sufficient side clearance to avoid metal interference and calibrate the gap voltage to the linear center. Additionally, as an M8 compact model, care should be taken to avoid excessive force on the coaxial connectors and ensure the total cable length matches the system design.
It is a 3300 NSv series eddy current proximity probe by Bently Nevada, specifically designed for tight spaces or small shaft diameters.
What is the primary use of 330903-03-11-05-02-05?
It is used for radial vibration and axial position monitoring of small centrifugal compressors, pumps, and motors.
Is the 330903-03-11-05-02-05 compatible with the 3500 system?
Yes, it integrates into the 3500 system via the matching 3300 NSv Proximitor.
What is 330903-03-11-05-02-05 operating temperature range?
The operating temperature range of the probe tip is -52°C to +177°C.
Is it recommended to repair the 330903-03-11-05-02-05?
Repair is generally not recommended; replacement is advised to ensure accuracy.
